A Study on Internet of Things Security and Lightweight Cryptography

Abstract

The Internet of Things (IoT) is the most hyped technology, which means that it is the hottest topic that has gained the most attraction of the researchers currently. In recent years, there have been huge amount of research have been done in different aspects of IoT. Internet of Things (IoT) connect to the Internet billions of heterogeneous smart devices with the ability of interacting with the environment. Meanwhile, providing privacy and security is an inseparable part of this technology. Without providing enough security, the promising benefits of this successful technology will be misused. In order to enjoy this new environment, security of constrained end nodes is important. If one of the nodes compromised, the network suffers seriously. However, it is not easy to implement sufficient cryptographic functions on constrained devices due to the limitation of their resources. This paper gives an overview of the lightweight cryptography, which can be implemented efficiently in constrained devices. This technology enables secure and efficient communication between networked smart objects.
